Device for sealing an opening in the front area of a rail-bound vehicle as needed, nose cone module with such a device and rail-bound vehicle with such a nose cone module

摘要

The device (1) has a frame (3) for carrying a sealing body (2) i.e. inflatable ridge-like bellows, of variable size, where the frame surrounds a region (4) together with the sealing body. A coupling shaft (12) of a central buffer coupling (11) is guided through the region. The body has an inflatable hollow chamber pneumatically or hydraulically controllable such that a surface covered by the body is enlarged during inflation of the chamber. The body is formed like a collar and has disks combinely rotatable by a mechanism towards the region, surrounded by the frame, for enlarging the surface. An independent claim is also included for a front end module for a track-guided vehicle.
